Modern aridity in the Altai-Sayan mountain range derived from multiple millennial proxies.

Sci Rep 2022 May 11;12(1):7752. Epub 2022 May 11.

Swiss Federal Institute for Forest, Snow and Landscape Research WSL, Zürcherstrasse 111, 8903, Birmensdorf, Switzerland.

Temperature and precipitation changes are crucial for larch trees growing at high-elevation sites covered by permafrost in the Altai-Sayan mountain range (ASMR). To contextualize the amplitude of recent climate fluctuations, we have to look into the past by analyzing millennial paleoclimatic archives recording both temperature and precipitation. We developed annually resolved 1500-year tree-ring cellulose chronologies (δC, δO), and used these new records to reconstruct the variability in local summer precipitation and air temperature.
